Jon had wished that he'd temporarily forget about the rock you see, so when he found himself transformed into a teenage girl, she was so overwhelmed by a mixture of shock, fear, and disgust that she hugged herself and started crying softly. She always thought it was sexy to see or read about men being turned into women, but she didn't expect it to happen in real life, especially not to herself.
Her mind raced with questions: How did this happen? Is this some higher power's idea of punishing me? How long will I stay like this? Who were those women who turned into men? What if they got me pregnant? She couldn't begin to guess at the answers. As far as Jon knew, she'd basically just been transformed and raped by a bunch of gender-changing ghosts that may or may not have impregnated her. The taste of semen from the last ghost was still fresh in her mouth, and she thought she was going to throw up.
Eventually, Jon managed to stand up, and looked at herself in the mirror. "Well, at least I'm a cute girl," she said, smiling grimly. That was the one positive in this situation, even her voice sounded different now. She put on her clothes and underwear that was on the bed, the fabric on her new body reminding her how much she'd changed. Not knowing what else to do, she did what most teenagers do when they're afraid and need someone's help.
"Mom! Mom, you've got to help me! Something terrible happened!" She cried, running out to look for her mother. Jon figured if her family was going to find out either way, she might as well be honest, and come right out admitting she was a girl now.
